arostm 0:4af3ca173992 38 User NOTES
arostm 0:4af3ca173992 39 1. How To use this driver:
arostm 0:4af3ca173992 40 --------------------------
arostm 0:4af3ca173992 41 - This driver is used to drive the touch screen module of the STM32F413H-DISCOVERY
arostm 0:4af3ca173992 42 evaluation board on the FRIDA LCD mounted on MB1209 daughter board.
arostm 0:4af3ca173992 43 The touch screen driver IC is a FT6x36 type which share the same register naming
arostm 0:4af3ca173992 44 with FT6206 type.
arostm 0:4af3ca173992 45
arostm 0:4af3ca173992 46 2. Driver description:
arostm 0:4af3ca173992 47 ---------------------
arostm 0:4af3ca173992 48 + Initialization steps:
arostm 0:4af3ca173992 49 o Initialize the TS module using the BSP_TS_Init() function. This
arostm 0:4af3ca173992 50 function includes the MSP layer hardware resources initialization and the
arostm 0:4af3ca173992 51 communication layer configuration to start the TS use. The LCD size properties
arostm 0:4af3ca173992 52 (x and y) are passed as parameters.
arostm 0:4af3ca173992 53 o If TS interrupt mode is desired, you must configure the TS interrupt mode
arostm 0:4af3ca173992 54 by calling the function BSP_TS_ITConfig(). The TS interrupt mode is generated
arostm 0:4af3ca173992 55 as an external interrupt whenever a touch is detected.
arostm 0:4af3ca173992 56
arostm 0:4af3ca173992 57 + Touch screen use
arostm 0:4af3ca173992 58 o The touch screen state is captured whenever the function BSP_TS_GetState() is
arostm 0:4af3ca173992 59 used. This function returns information about the last LCD touch occurred
arostm 0:4af3ca173992 60 in the TS_StateTypeDef structure.
